9- Claims.

This invention relates to combination radio and phonographic units, andmore particularly to units employing an automatic record changer.

Automatic record changers have been employed in connection withphonographs for a number of years. More recently, they have been usedquite widely in combination radio and phonograph units. In view of thefact that automatic record changers involve considerable op-- cratingmechanism, they are more or less bulky in size. These automatic recordchangers in combination radio and phonograph units are usually disposedin a relatively deep well in the top of the radio cabinet which isaccessible by opening the lid of the radio cabinet. In other instancesthey are mounted substantially on top of the radio cabinet but beneath alid having a relatively deep skirt or side wall which conceals the unitwhen not in use. These arrangements for the most part have either beenunsightly in appearance or else not readily accessible to the person whowishes to play the machine.

It is an object of the present invention to provide a novel radiophonograph construction in which the automatic record changer andphonograph unit may be quickly and easily brought to an accessibleposition, but which may be retracted to a concealed position when not inuse.

It is a further object of the present invention to provide a novelradiophonograph carriage and cabinet in which the phonograph unit ismounted on a movable carriage which. may be partially withdrawn from theradio cabinet when the phonograph is to be played.

Another object of the present invention is to provide a novel cabinetconstruction for combination radio and'phonograph units in which thephonograph unit is mounted on a slidable carriage which is partiallywithdrawn from the radio cabinet when one or more doors on the front ofthe cabinet are opened.

Another and still further object of the present invention is to providea novel supporting and mounting structure for the turntable andassociated mechanism of a phonograph or other record player.

The novel features which I believe to be characteri'stic of my inventionare set forth in particularity in the appended claims. My inven-= tionitself, however, both as to its organization and manner of construction,together with further objects and advantages thereof, may best beunderstood by reference to the following description, taken inconnection with the accompanying drawings, in which:

Figure l is a front perspective view of a combination radio andphonograph unit;

Figure 2 is a rear elevational view of the combination radio andphonograph unit shown 1 Figure 1;

Figure 3 is a plan view of the phonograph supporting carriage in itsretracted position within the radio cabinet;

Figure 4 is a view similar to Figure 3 but showing the phonographsupporting carriage in its withdrawn position; and,

Figure 5 is a vertical sectional view along the line VV of Figure 3.

A combination radio and phonograph unit as shown in Figures 1 and 2 ofthe drawings includes a cabinet II which houses an automatic phonographand record changer unit l2 and a radio l3. The radio [3 is mounted inthe upper portion of the cabinet H and is equipped with theusual'control knobs M, a dial l5, and a set of push button controls I6.The phonograph and record changer unit I2 is carried below the radiounit 13 partially on and partially within a housing H which is arrangedto slide out of the cabinet II when the two cabinet door l8 are opened.A power cable I9 to operate the mechanism of the phonograph unit I!extends from the radio I3 as is shown in Figure 2. The pick up head 20of the arm M is electrically connected to the radio set in theconventional manner through a cable 22.

The phonograph-unit l2 as shown includes a turntable 23 having a centerspindle 24 over which a stack of records are placed and seated on theautomatic record changer arms 25.

Referring now particularly to Figures 3, 4 and 5 of the drawings, itwill be seen that the housing or carriage ll of the phonograph unit I2is provided with a pair of rollers 26 on each side thereof. The housingor carriage I! as shown contains the principle operating mecha-- nism ofthe phonograph and record changer unit.

The rollers 26 ride in a 'pair of metal channels 21 on opposite sides ofthe casing or carriage H which in turn are carried in wooden crossarms28 which are channeled out to receive the channel bars 21. These woodenbars 28. are secured to the crossbar 29 at the rear of the cabinet IIand to the crosspiece 30 at the front of the cabinet. Reinforcing blocks3| are preferably secured to the rear of the bars 28 and the crossbar 29in the manner as shown in Figures 3, 4 and 5.

The rollers 26 riding in the metal channel bars 21 provide the necessarysupport for the casing or carriage I! of the phonograph and recordchanger unit l2.

Two guide roller elements 32 depending from the casing I! ride in achannel bar 33 to prevent lateral shifting of the casing IT. The channelbar 33 is mounted on the rear crossbar 29 and the front crossbar 30 andis suitably secured thereto in any convenient manner.

The doors IE on the front of the cabinet II are mounted on cabinethinges 34 and are provided with knobs or handles 35, which enables themto be swung open at will. Secured to each door 18 is a rearwardlyprojecting metal plate 36 which is mounted on the rear face of eachdoor. This rearwardly projecting metal plate 36 is equipped with anupwardly projecting roller element 31 which is free to rotate on theplate 36. In the bottom of the casing i! there are formed two slots 38which extend at a slight angle to the front face of the casing H. Theroller element 31 on the plate 36 of the doors l8 extend up and ride inthese slots 38. From an examination of Figures 3 and, 4 of the drawingsit will at once be apparent that as the doors l8 are swung open thecasing I! will be partially withdrawn from within the cabinet ll.Suitable stop means (not shown) are provided to limit the outwardmovement of the casing l1 and to prevent the front rollers 26 fromdropping out of their respective channel tracks 21.

As is clearly shown in Figure l, the phonograph and record changer unitI2 is withdrawn to a sufficient extent by the opening of the doors I 8to render the turntable readily accessible by the person wishing tooperate the machine. In this position a stack of records (not shown) maybe placed over the center spindle 24 on the supporting arms 25, and thedoors l8 may then be closed and the phonograph unit placed in operationin conjunction with the radio l3.

The particular typeof arrangement which has been illustrated anddescribed has been found 1 to be particularly satisfactory since thephonograph and record changer unit may be disposed in the interior ofthe cabinet II in a concealed position during ordinary use of the radioand during actual playing of the phonograph itself, and yet at the sametime it may be readily and quickly moved out to an accessible positionby simply opening the front doors of the cabinet.

While I have shown a particular embodiment of my invention, it will, ofcourse, be understood that Ido not wish to be limited thereto, sincemany modifications may be made, and I therefore contemplate by theappended claims to cover all such modifications as fall within the truespirit and scope of my invention.
